GetColumnSQLVARIANTToString Method
この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。新規の開発作業ではこの機能を使用しないようにし、現在この機能を使用しているアプリケーションは修正することを検討してください。
The GetColumnSQLVARIANTToString method converts a sql_variant column to a string and returns its value.
構文
object
.GetColumnSQLVARIANTToString(
Row
,
Column
,
ObjName
)
as String
Parts
- object
Expression that evaluates to an object in the Applies To list.
- Row
Long integer that identifies a row by ordinal position.
- Column
Long integer that identifies a column by ordinal position.
- ObjName
String that specifies a table or view name.
Prototype (C/C++)
HRESULT GetColumnSQLVARIANTToString(
long lRow,
long lColumn,
SQLDMO_LPCSTR ObjName,
SQLDMO_LPBSTR pRetVal);
メモ : |
---|
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |
解説
GetColumnSQLVARIANTToString can be useful in applications designed to display the contents of sql_variant columns, such as a Web site.
Columns with underlying numeric, decimal, or datetime data types cannot be converted to strings using the GetColumnSQLVARIANTToString method.
メモ : |
---|
If an application calls GetColumnSQLVARIANTToString on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned. |
